GAS-ENGINE.

SPECIFICATION forming part of Letters Patent No. 283,398, dated August 21, 1883. Application fi ed December 28, 1882. (N mmlchh To all/l whom it may concern:

Be it known that we, JOHN F. JACKSON and DAVID M. KIRKPATRICK, citizens of theUnited States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Gas-Engine, of which the following is a specification, reference being had to the accompanying drawings. This invention relates to an improved engine for marine propulsion and for other purposes and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure l is a longitudinal vertical sectional view of part of the hull of a vessel, showing in elevation the several parts constituting our improved engine complete. Fig. 2 is a longitudinal vertical sectional view of the boiler and furnace.

Fig. 3 is a vertical transverse sectional view of the same. Fig. 4 is a vertical sectional view of one of the cylinders and valve-chests. Fig.

- 5 is a longitudinal vertical sectional view of the condenser and reserve-tank. Fig. 6 is a vertical transverse sectional view of the same, and Fig. 7 is a horizontal sectional view taken through the condensing-tank and parts of the hull adjoining.

The same letters refer to the same parts in all the figures.

This invention relates to gas-engines; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.

' lar boiler, is denoted by letter D.

gage-glass E, pressure-gage F, and domesG H,

In the drawings, A represents part of the hull of a vessel equipped with our improved engine. 13 may represent the boiler-room, and

C the engine-room; but we would have it understood that the parts may be located differently and in any suitable manner.

The boiler, which maybe an ordinary tubul't has the said cylinders with double or extra caps M, in order to secure tight j oints, and to guard against 1 the loss of power resulting from overtight packing. I 55 N N are the pistons; O O, the pistonrods; P P, the crossheads; Q, Q, the guides for the latter, and It It the pitmen or connectingrods, which serve to communicate the motion of the stroke from the piston-rods to the crank of the main shaft,which latter, however, is not shown in the drawings, and which may be constructed and arranged in any suitable and convenient well-known manner.

S S represent the valve-chests, to which the vapor is conducted from the boiler-dome G through a pipe, T. Thevalvcs U U may be operated by any suitable mechanism connecting their stems V V with an eccentric upon the main shaft. This mechanism, however, is not shown in the drawings, and it forms no part of the present invention. The valvechests are connected with the cylinders by suitable passages, providing, in the usual man ner, for the admission and exhaust of the vapors.

W WV are the exhaust-pipes, which connect the steam-chests with a condensing-tank, X, located in the hold of the vessel, and provided with an air-valve, Y, and vacuum-gage Z.- The tank X is located above, and connected by a neck, A, with another tank, B which we call the reserve-tank.

- 0 W are pipes extending longitudinally through the tank X, and extending through 5 the sides of the hull below the water-line, as shown at D It will be thus understood that when the vessel is under way, and also, to some extent, when it is stationary, currents of water are constantly passing through the pipes 0 C thereby cooling the interior of the condensingtank and causing the vapors conducted into the latter to condense, when they will pass through the neck A into the lower reservetank. The latter is connected by a pipe, E, with the boiler. Pipe E is equipped with a suitably-constructed injector, F by means of which the condensed liquid may be forced from the reserve-tank into the boiler.

Some suitable provision may be made by which the vapors may be utilized in the furnace for generating the heat necessary for vaporizing the contents of the boiler. To compensate for the liquid thus utilized for heating, as well as for illuminating purposes, additional liquid may,when necessary, be introduced into the reserve-tank B through a filling-tube, G",with which the latter is provided.

From the foregoing description, taken in connection with the drawings heretoannexed, the operation and advantages of our invention will be readily understood. By the substitution of the vapors of light volatile oils for steam as a motive power the first and principal advantage is gained. Such oils are vaporized at a much less'degree of heat than water, and consequently a great saving of fuel is effected. There being no sediment, the boiler will be always clean and free from incrustation. Owing to the lubricating qualities of the vapors, the engine will bear tight packing, and will always run smoothly and without oiling, except in places to which the vapors have no access.-

By the construction and arrangement of the condenser, as described, waste of the vaporgenerating liquid is totally avoided, and it will require replenishing only to compensate for such portions of the same as may be used for The condensing mechanism is simple, and' is constantly in operation, absolutely without expense.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States The combination and arrangement, substantially as described, of the boiler, the feedpipe, the cylinders and valve-chests, the exhaustpipe, the condensing-tank having pipes eX- tending longitudinally through the same and through the sides of the hull, the reserve-tank located below and connected with the condensing-tank, and the injector-pipe connecting the said reserve-tank with the boiler, sub stantially as set forth.

, In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
